A design of broadband slow-wave delay line performed in X-band is presented .Basic concepts of the slow-wave delay line are introduced .The layout of the branch length , branch spacing distance , branch width and bend shape are optimized by using electromagnetic simulate software .Miniaturization structure is realized and broadband performance is enhanced .Simulation and ex-perimentation prove that meander line can achieve high delay efficiency up to 200%, low port reflect coefficient less than -25 dB and phase linearity in band less than 8°, in contrast to conventional trace forms .
